Name |
phosphosulfolactate synthase;
(2R)-phospho-3-sulfolactate synthase;
(2R)-O-phospho-3-sulfolactate sulfo-lyase
|
Class |
Lyases;
Carbon-sulfur lyases;
Carbon-sulfur lyases (only sub-subclass identified to date)
|
Sysname |
(2R)-2-O-phospho-3-sulfolactate hydrogen-sulfite-lyase (phosphoenolpyruvate-forming)
|
Reaction(IUBMB) |
(2R)-2-O-phospho-3-sulfolactate = phosphoenolpyruvate + sulfite [RN: R07476]
|
Reaction(KEGG) |
|
Substrate |
(2R)-2-O-phospho-3-sulfolactate
|
Product |
|
Comment |
Requires Mg2+. The enzyme from the archaeon Methanococcus jannaschii catalyses the Michael addition of sulfite to phosphoenolpyruvate. It specifically requires phosphoenolpyruvate and its broad alkaline pH optimum suggests that it uses sulfite rather than hydrogensulfite.
